In Pictures: The World's 10 Most Wanted Fugitives

Semion Mogilevich

The face of Russian organized crime was briefly arrested in 2008 in Russia amid accusations of tax evasion at a cosmetics retailer. As a result he was excluded from Forbes' first Most Wanted list. His lawyers said Mogilevich was innocent of the tax charges, and he was released in 2009. The U.S. has asked that he be handed over in connection with a $150 million stock fraud, but with no extradition treaty between the U.S. and Russia, there seems little chance of it. "We didn't look at this as purely a financial fraud but one of many activities of an organized crime group," says FBI Special Agent Michael Dixon, who adds Mogilevich has been linked to allegations ranging from murder-for-hire to weapons trafficking to possibly trafficking in nuclear materials. Mogilevich has denied such accusations.
